Michael Eisner and Don Simpson argued over who originated the idea until Simpson died; Gilbert Hill was a real Detroit detective; the theme reached number three on the Billboard chart; a 2013 CBS pilot with Brandon T. Jackson as Axel's son failed; Eddie improvised much of an Oscar-nominated screenplay
The origin is claimed by Michael Eisner, who on a podcast with the host told the story of a 1975 speeding ticket from a cop who seemed a bit of a dick gave him the germ of a movie about a Hollywood police officer; Don Simpson, who worked for him, had a 1977 idea about an East LA cop transferred to Beverly Hills but could not get a screenplay done; Eisner's lesson that being pulled over in a beater meant he needed a Mercedes-Benz is called the most privileged thing ever heard.
Nobody planned on a black cop, so it is a high-level irony that a what-if-Stallone, pride of Italian Americans, vehicle became salient commentary neither Eisner nor Simpson intended; Simpson had just made Flashdance, and the two argued about the origin until Simpson died.
Gilbert Hill, the Detroit police lieutenant, was an actual Detroit detective who appeared in only three movies; 48 Hours is suggested as the first instance of giving the lone black character in a movie the most powerful job with 30 seconds of screen time, a pattern that kept happening.
The theme to Beverly Hills Cop reached number three on the Billboard chart, with Neutron Dance, The Heat Is On, Stir It Up and New Attitude also in the film; in 2013 The Shield creator Shawn Ryan tried a Beverly Hills Cop TV show, a CBS pilot with Brandon T. Jackson as Axel Foley's son that did not work.
Writer Daniel Petrie and director Martin Brest carried pieces of different screenplays; according to Petrie, Eddie would take a line, expand it and put it in a comic persona invented for the moment, and according to Brest, whenever they got in a jam he asked Eddie for something and it knocked him to the floor; the movie was nominated for best screenplay though Eddie improvised about two thirds of it.
